Giuliana- Please do not take this the wrong way, because it did turn out very good, but I would just like to give you and everyone else a few little tips for those tackling this project (or similar projects) on their own.

1. Use a guide (straight piece of wood like a 2x4 works) to keep your edges straight. Also use a landscapers shovel (completely flat with no rounded edges) to dig out your boarder which will help keep the edges straight and neat.

2. When you install the scalloped edging (or other landscaping stones) bury them (in tier landscaping bury the bottom stone 1/2-3/4 of the stones height into the ground) about halfway into the ground to keep them from moving, falling over, shifting etc. (basically it helps keep them in place and looking good for years to come).

3. After you get the grass/ weeds out of the area you are working with put a layer of newspaper down, then a weed barrier (mesh or plastic, can be found at home depot/ lowes or other hardware/ landscaping stores) before installing your mulch or stones. If you are going to plant flowers or shrubs in the area either cut the newspaper and weed barrier around the plant after you install them, or tuck them around the flower/ shrub. Also before you install your mulch or stone I like to put down a weed preventative like Preen (also found at home depot/ lowes and many others).

While these little extras will cost a little bit more, and take a little more time they are all worth it :-D
